Motherhood is all-encompassing, and in a way, as the mother, you're the star of the household.

For a while I used to listen to those whispers about babies costing you books, and Cyril Connolly's loathsome quote that "There is no more somber enemy of good art than the pram in the hall." But it's rubbish. Absolute rubbish. A huge amount of your work is done when you're not at your desk. Knotty problems that you need your unconscious to solve. So it can be helpful to walk away and focus on other things and it can be helpful to be a bit harassed in your daily life, to be hungry for time to write.

I try not to be too precious about my writing, and I try to be willing to walk away from it for a few hours when something's not working, to let things percolate a bit. I try not to hide myself away from life too much, because I think that's a risky thing for a writer to do.

You need a lot of energy to get a novel finished. You need an ability to ignore everyone around you. It's why I don't read my reviews any more. I know a lot of people say that, but I really don't read them.

People had tell me the most personal things. People I'd never met before would say thing like "Oh, that was the summer I had an affair with my neighbor." The 1976 heatwave occupies a peculiar place in people's psyches.

When I worked at The Independent newspaper, I had colleagues who would laugh and say that whenever they picked up the phone to my dad and heard his accent, they thought they were about to hear a five-minute warning to get out the building. People in Britain have always thought it acceptable to make racist remarks about the Irish. The prejudice underlying that supposed joke was everywhere.

Something that had an enormous influence over my relationship with language was my stammer. I had a really bad stammer in my childhood and adolescence, and that imbues you with two things. First, a hyper-sensitivity to grammar, because a stammerer will have problematic sounds, impossible verbal stumbling blocks. Second, writing is just such a joy when you have a problem with speaking. It's so astonishing to watch language coming out of your pen without any hesitation or dysfluency.
